CARL 3'. LINDQUTST, OF NEW YORK. N. Y.

WEATHER STRIP.

Application filed February 16, 1923. Serial No. 619,335.

To all whom it may concern.

Be it known that I, CARL J. LINDQUIST, a citizen of the United States ofAmerica, residing at New York city, county and State of New York, haveinvented certain new and useful Improvements in Weather Strips, of whichthe following is a specification.

This invention relates to improvements in window constructions and inparticular to weather strips therefor of a novel type.

An object of the invention is to provide on the parting strip animproved weather strip which will extend into grooves on the adjacentsashes, the strip being so constructed and designed as to provide a rainshield and which will at the same time, when in position, conceal thegroove. My improved strip can be applied without removing the sashes.

A further object of the invention is to provide a weather strip whichwill not deteriorate with time or change its shape due to atmosphericconditions, the longitudinal corrugations tending to maintain the stripin proper shape at all times and the strip having sufiicient resiliencyto accommodate itself to irregularities in the grooves or warping of thesashes.

Referring to the drawing, wherein several embodiments of my inventionare disclosed;

Fig. 1 is a sectional plan view taken through a sash showing theapplication of my improved weather-strip thereto;

Fig. 2 is a view of a part of Fig. 1 showing the application thereto ofa modified form of weather strip;

Fig. 3 is an enlarged top plan view of a portion of a weather stripshowing its engagement with a groove in a sash; and

Fig. 4: is a view in perspective of a piece of Weatherstrip which hasincorporated therein a filler of felt or rubber.

Referring to the drawings in detail, 5 indicates the lower sash of awindow which has sliding movement in a well known manner between thesash stops 6 and parting strips 7, the two being joined by the usualpulley stiles 8 which border the edges of both the lower and uppersashes. The parting strips 7 separate the sashes and a description of myinvention as applied to one parting strip and one side of one sash willserve to illustrate its use.

The spaces between the sash and the frame of the window admits air andrain if there is no method used of sealing the same, and

my weather strip 9 when applied as shown in Figs. 1, 2 and 3 preventsadmission of air and rain and also besides concealing the groove cut inthe sash takes up wear of the edges of said groove.

In the form of Weatherstrip shown in Figs. 1 and 3, T provide a strip ofmetal 9, such as zinc or copper which is not liable to corrosion andwhich is bent adjacent its longitudinal edges to provide corrugations orridges 10, one of which is or may be disposed on each side of theparting strip 7 when the Weatherstrip is attached thereto by nails 11 asindicated.

Suitable grooves 12 are provided in the sashes adjacent the partingstrips 7 into which extend the edges of the weatherstrips 9, until thecorrugations 10 thereof rest on the edges of the grooves as shown inFig. 3 to seal and conceal the same and thus provide a closure for thespace between the sash and frame.

As shown in Fig. 2, I may provide the edges of the strip 9 with beads 13which are formed by bending the strip edge over to fo m an enlargedloop. These beads are disposed within the grooves and engage the sidewalls of the latter, thus more effectively sealing the opening betweenthe frame and the sash.

In Fig. 4t I have shown a piece of a strip similar to the one having thebeads 18 thereon, with the exception that this strip is pro vided with afiller or backing 1a, the edges of which are held under the beaded edges13 of the Weatherstrip 9. This filler may be of rubber or felt.

The strips 9 may be fastened to each parting strip 7 and engage groovesin the lower and upper sash simultaneously, so that both sashes aremaintained weatherproof.

It can be readily seen that the weatherstrips can be applied to thesashes without removing any part of the window framing or structure andare simply nailed to the parting strip and extend the length thereof.The strips 9 are provided with suitable nail holes 15 in manufacturewhich facilitates their being applied.

Any shrinkage of the sashes or structure to which the strip is attachedis taken up, as the corrugated portion of the strip is sufficiently wideto always be self-seating on the groove edge and therefore seal thesame.

What I claim is:

1. In combination, a parting strip of a Window construction, sash stilescoacting therewith, said stiles having grooves therein, a Weatherstripattached to said parting strip and engaging the grooves in said stilesand said Weatherstrip having angular ridges there-in each engaging anedge of the adjacent one of the grooves in said stiles.

2. In combination, a parting strip of a window construction, sash stilescoacting therewith, said stiles having grooves there in, a Weatherstripattached to said parting strip and engaging the grooves in said stiles,and said Weatherstrip having angular ridges therein, and beads formed onthe edges thereof, said beads lying Within said grooves aid said angularportions each en aging an dge of the adjacent one of the grooves in saicstiles.

3. In combination, a parting strip of a n ndow construction, sash stilescoaoting 20 7; herewith, said stiles having grooves there- 11. aWeatherstrip attached to said parting strip and engaging the grooves insaid stiles,
